 This is similar to #42522 but subtly different.

 When a post transitions from one status to another, term counts for the
 terms of the post are unnecessarily recalculated even when neither the old
 status or the new status are statuses which are included when counting
 terms. An example is when an autosave is first created.

 In simpler terms, term counts for a post should only be recalculated when
 either its old or new status is `publish`. It just needs to respect other
 statuses added via the `update_post_term_count_statuses` filter too.
